About
Prometheus is an industrial AI startup founded in late 2025 and publicly launched in November 2025, led by Amazon founder Jeff Bezos and former Google X executive Vik Bajaj 12. The company is building AI tools to help engineers design and manufacture physical products, with the stated ambition of creating an “artificial general engineer” — a system envisioned as capable of taking a complex physical product like a jet engine from concept through production 3. The startup employs roughly 150 people and operates GPU infrastructure for AI model development 1.
Bezos described the company’s mission as compressing lengthy manufacturing cycles: “The cycle from dream, to manufacturing at rate, to having it out in the world can be very long” 2.
